Value Collection 97221 Hex Head Cap Screw Grade 5 Steel

Product Description

The VALUE COLLECTION 97221 is a hex head cap screw designed for general-purpose mechanical fastening in structural and equipment assembly applications. It features a 1-8 UNC thread size and a 3-3/4 inch length under head, with partial threading along the shank. Manufactured from Grade 5 steel with an uncoated finish, this fastener meets the dimensional and mechanical requirements of ASME B18.2.1 and SAE J429. It is installed using a standard hex wrench or socket and is suited for moderate-strength bolted joint applications across a range of industries and trade settings.

This screw is appropriate for use in mechanical, structural, and equipment maintenance applications where an inch-series UNC fastener is specified. The partial thread design provides a grip length on the shank, making it suitable for joints where clamp load and shear strength are both considerations. Licensed trades including HVAC technicians, plumbers, electricians, and general maintenance mechanics commonly use Grade 5 hex cap screws for equipment mounting, panel fastening, and structural connections. Sold in a package quantity of 15 with a minimum order quantity of 1.

Installation Notes

Installation requires a properly sized hex socket or open-end wrench matched to the hex head drive size. Follow applicable torque specifications for Grade 5 fasteners as defined by the joint design engineer or equipment manufacturer. Ensure mating threads are clean and free of debris before installation. Consult applicable mechanical or structural codes for torque and clamp load requirements in safety-critical joints.
